The butterfly effect Slow Knuckle, slow pitch, butterfly and flat fall, are all terms related to butterfly jigs, a family of small, 40-300g, oblong, flat profile "fluttery" jigs. Butterfly jigs first became popular in Asia, especially Japan. They do work in New Zealand with a slightly modified fishing style: fish the bottom 4-5 metres hard (in a workup they will work at whatever depth the fish are). Targeting snapper hard on the bottom is best, and the rise/freefall action is key. Find the bottom with the lure then wind the lure up 1m while lifting your rod tip as high as you can get it, then drop the rod tip and point it directly at the same angle as your line so the lure freefalls; repeat for another four cycles (4x1m), then free-spool to the bottom and repeat. You'll look like a conductor with a baton pointing to the sun at the top stroke, but if the fish are there and feeding you'll catch some, the buzz/hum/vibration of these lures is well proven. It's a lot more aerobic than fishing inchikiu lures, but it's great fun. Getting hit on the drop and having the line pull straight of the end of the rod is pretty cool. Use a parabolic rod (bendy top 45%, with a stiffer 55% bottom) with 10-15lb maximum braid on an overhead bait cast or small round reel. A fluorocarbon leader of 20lb maximum, it's abrasion-resistant and almost invisible (yo-zuri pink fluoro is best). Butterfly jigs can also be used for shore jigging - that's lure fishing from shore where conditions and sea floor structure allow. Tip of the day: rig your butterfly jig with an assist hook on the same end you tie the leader to.
